I recently washed over 200 pieces of batik and I am sure that almost all of them bled - some more than others. I have pieces from fat quarters to 4 yards. I put a drop or two of liquid soap in my pure white dish pan and just laid the pieces in the water, still folded, and gently swished them around. Then drained the water and used clear cool water for the rinse and had to rinse and rinse many of them until the water was clear. I then put big thristy towels on my kitchen counter and unfolded the pieces and rolled them up in the towels and kept them rolled up for 30 minutes or so. Then, unrolled them and hung them up on clotheslines that I had my DH put up in our family room - nice and warm in there. When dry, I just folded them back up and put in piles of 25 on a table and was shocked that I had over 200 pieces. They did not get very wrinkled at all - but when I use them, I will iron them then. I had to throw away at least two pieces as they never did stop bleeding. HTH
